Boston, May 31  Stanford scientists have developed a more stable prosthetic foot which they say could make challenging terrain more manageable for people who have lost a lower leg. The new design has a kind of tripod foot that responds to rough terrain by actively shifting pressure between three different contact points. "Prosthetic emulators allow us to try lots of different designs without the overhead of new hardware," said Steven Collins, an associate professor at Stanford University in the US. "Basically, we can try any kind of crazy design ideas we might have and see how people respond to them," he said, without having to build each idea separately, an effort that can take months or years for each different design. People with a leg amputation are five times more likely to fall in the course of a year, which may contribute to why they are also less socially engaged. A better prosthetic limb could improve not just mobility but overall quality of life as

One idea for how the universe began is that the universe may have appeared out of nothing due to some quantum effect, such as quantum tunneling. In the 1980s, Stephen Hawking and James Hartle further elaborated on this idea by suggesting that time did not exist before the beginning of the universe, leading them to conclude that the universe has no initial boundary conditions on either time or space.

LONDON Astronomers say they have discovered a rogue exoplanet with its own atmosphere in the Neptunian Desert. NGTS-4b, nick-named 'The Forbidden Planet' is smaller than Neptune but three times the size of Earth, said researchers led by the University of Warwick in the UK. The exoplanet, described in the journal Monthly Notices of the Royal Astronomical Society, has a mass of 20 Earth masses, a radius 20 per cent smaller than Neptune, and temperature of 1000 degrees Celsius. It orbits around the star in only 1.3 days—the equivalent of Earth's orbit around the Sun of one year. It is the first exoplanet of its kind to have been found in the Neptunian Desert, researchers said. The Neptunian Desert is the region close to stars where no Neptune-sized planets are found, they said. This area receives strong irradiation from the star, meaning the planets do not retain their gaseous atmosphere as they evaporate leaving just a rocky core. However NGTS-4b still has its atmosph

WASHINGTON: Scientists have discovered a way to identify indicators of a mega earthquake using GPS-based information, an advance that may help improve early warning systems for quakes. The researchers from University of Oregon in the US combed through databases of earthquakes since the early 1990s have discovered a possible defining moment 10-15 seconds into an event that could signal a magnitude seven or larger quake. Likewise, that moment—gleaned from GPS data on the peak rate of acceleration of ground displacement—can indicate a smaller event. GPS picks up an initial signal of movement along a fault similar to a seismometer detecting the smallest first moments of an earthquake. Such GPS-based information potentially could enhance the value of earthquake early warning systems, said Diego Melgar, a professor in the University of Oregon. The physics-heavy analyses of two databases detected a point in time where a newly initiated earthquake transitions into a slip pulse where mecha

WASHINGTON: Rocks on the surface of Mars that look like layers of pasta may be the most obvious sign of life on the Red Planet, a NASA-funded study suggests. The bacterium that controls the formation of such rocks on the Earth is ancient and thrives in harsh environments that are similar to conditions on the Mars, according to the study published in the journal Astrobiology. “It has an unusual name, Sulfurihydrogenibium yellowstonense. We just call it ‘Sulfuri’,” said Bruce Fouke, a professor at the University of Illinois in the US. The bacterium belongs to a lineage that evolved prior to the oxygenation of Earth roughly 2.35 billion years ago, Fouke said. It can survive in extremely hot, fast-flowing water bubbling up from underground hot springs. It can withstand exposure to ultraviolet light and survives only in environments with extremely low oxygen levels, using sulphur and carbon dioxide as energy sources. “Taken together, these traits make it a prime candidate for colonisi

NEW DELHI A century ago, a few adventurous astronomers pointed their telescopes at the skies, observing one of the most famous solar eclipses that helped transform our understanding of the universe forever. The event helped verify Albert Einstein's General Theory of Relativity which underpins critical modern technologies such as the satellite-based Global Positioning System (GPS). The theory is essential for the correct operation of GPS systems, which in turn are relied on in many common applications including vehicle satellite navigation (SatNav) systems, weather forecasting, disaster relief and emergency services. "This observation not only confirmed a fundamental theory of nature, and enhanced our understanding of nature in a great way, but also showed the genius of Einstein," Sudip Bhattacharyya, Associate Professor at Tata Institute of Fundamental Research (TIFR) in Mumbai told PTI.

Between 2009 and 2015, the legislation more than doubled the fuel efficiency of the fleet of 13,500 yellow taxis, leading to estimated declines in air pollution emissions. from Latest Science News -- ScienceDaily http://bit.ly/2JLYZLb

BRCA DNA-repair proteins interact with a molecular complex that is also responsible for regulating the immune system. When certain players in this pathway go awry, autoimmune disorders arise. An international team has deciphered the structure of the complex and have found new molecular targets for fighting autoimmunity. from Latest Science News -- ScienceDaily http://bit.ly/2I2WHUQ

Taxes on sugary products and labels on the front of packages can help reduce sugar consumption, according to a new study. The study, which included more than 3,500 people aged 13 and over on their purchasing behavior last spring, also found that taxes could have the greatest impact if 100 per cent fruit juice was included in reduction efforts. from Latest Science News -- ScienceDaily http://bit.ly/2X9zreg

Without significant global reductions in greenhouse gas emissions, Colombia will have 60% less land suitable for rice production by the 2050s. Due primarily to increased temperatures and decreased rainfall -- as opposed to sea-level rise, which is the driver of projected change to rice production in some Asian countries -- the research shows suitable conditions will need to be found at higher elevations when low-altitude fields are too hot or dry for irrigated rice. from Latest Science News -- ScienceDaily http://bit.ly/2Wd7END

WASHINGTON Rocks on the surface of Mars that look like layers of pasta may be the most obvious sign of life on the Red Planet, a NASA-funded study suggests. The bacterium that controls the formation of such rocks on Earth is ancient and thrives in harsh environments that are similar to conditions on Mars, according to the study published in the journal Astrobiology. "It has an unusual name, Sulfurihydrogenibium yellowstonense. We just call it 'Sulfuri'," said Bruce Fouke, a professor at the University of Illinois in the US. The bacterium belongs to a lineage that evolved prior to the oxygenation of Earth roughly 2.35 billion years ago, Fouke said. It can survive in extremely hot, fast-flowing water bubbling up from underground hot springs. It can withstand exposure to ultraviolet light and survives only in environments with extremely low oxygen levels, using sulphur and carbon dioxide as energy sources. "Taken together, these traits make it a prime candida
